WRAPPING-MACHINE.

Specification of Letters Patent. Patented NOV. 21, 1911.

' Portland, in the county of Multnomah and State of Oregon, haveinvented certain new and useful Improvements iiil\rapping-Machines; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to the construction ters Patent No. 952,273 wereissued to myself and Robert Tucker on March 15, 1910; but it is to beunderstood that the features of construction of the apparatus of thepatent referred to, while particularly well suit-- ed for use inconjuncti'ouwithmy present invention, are to be considered as merelyillustrative of one form of mechanism for performing the wrappingoperations which precede the wrapping or folding-operation effected bythe devices that are the subject of this invention.

The present invention provides simple means for so folding a wrapperabout anarticle of merchandise that the final folds of the wrapper ateach end of the article to be wrapped shall lie against the same side ofthe article, to thus form what is co1nmonly called a back fold.

In the drawings chosen for the purpose of illustrating my invention, thescope whereof is pointed out in the claims, Figure 1 is a side elevationof a wrapping machine embodying, my invention; Fig. 2 is an enlarged,vertica l, central section of the apparatus shown in Fig. 1, the wrappersupply reel and its supporting standard being omitted and portions ofthe feed'plunger and knife actuating mechanism being. shown inelevation; Figs. 3 to 8. inclusive, are detail views showing ,thesuccessive positions assumedby the several folding devices dur ing thewrapper folding operation; Fig. 9

is a detail view showing, in plan, the relation of the pivotedsupporting blade or tongue to the spring-pressed folder blades which arelocated at the delivery end of the machine; Fig. 10 is a detail section,taken n the plane of the line 1.0-10, Fig. S), showing a partiallywrapped article passing this point; Fig. 11 is a detail section, takenin the plane of the line 11'-11, Fig. 9, showiiig a completely wrappedarticle passing to the delivery chute; Fig. 12 is a. detail perspectiveview of the pivoted blade or tongue for supporting the partially wrappedarti cle as it passes to the folder blades by which the final foldingoperation is effected; Fig. 13 is. a perspective view showing acompletely wrapped article.

Like symbols refer to like parts wherever they occur.

I will now proceed to describe my invention more fully so that othersskilled in the art to which it appertains may apply the same.

The organized apparatus which is illustrated in the drawings consists ofmechanism for feeding separate wrappers across the path of the articleto be wrapped, mecha nism for successively delivering the articles froma magazine to a movable receiver into which the wrapper is forced orcarried by the article of merchandise and by which the wrapper ispartially wrapped around the.

article, folding mechanism for completely folding the wrapper around thearticle, and mechanism for releasing the article of mer chandise fromthe receiver by which it is transported to permit its delivery from themachine.

Except the as hereinafter described.

' mechanism for performing the several functions above noted may, asshown in the drawings, conveniently be the same in construction andoperation asthat shown and described in Patent Number 952.273 heretoforereferred to. and. therefore. it will be unnecessary to herein describeanything more than the novel features of the wrapper folding mechanismwhich are the subject of this invention.

In the drawings the devices for performing thefinal wrapper foldingoperationuunisist of a pair of parallel blades 1 and '2 between whichthe article of merchandise is compelled to travel after it has been released from the article holder 74 and is ing pushed forward by theejector member 96 of the carrier head 79. As shown more particularly inFigs. 1 and 2, these blades may be conveniently mounted on asupporting'member 120 which is preferably curved upwardly at its innerend to afford a -mounting for a pivotally movable curved tongue 7 whichis so arranged adjacent to the. revolving carrier by which the articleof mechandise is transported as to sustain and support the partiallywrapped article after it has been released from the article holder 7% ofthe carrier. In order that the folder blades may automatically adjustthemselves to permit the passage between them of articles which varysomewhat from the normal size, as well as for the purpose inf-causingthe inner vertical faces of the blades to be firmly pressed against theend folds of thewrapped article, it is preferred to so mount said folderblades on the sup-f porting-member 120 that they may move toward andfrom each other to thus vary 1 thewwidth of the chalmel formed betweenthem,- a convenient means for effecting I this result consisting ofsprings 128 which bear upon the blades and uponwashersthat are carriedby screws 129 which pass loosely through said blades and have threaded.engagement with the supporting member 120. The folder blades 1 and 2,which, if desired may ,be made 1 of sufficient length to constitute adelivery chute for the wrapped article, are provided with inwardlyextend:

portion of the flange 4 overlapping and being longer than the taperingportion 3 of the flange 3. This relation of the tapered portions of theflanges 3 and 4 permits the folds in thewrapper which are effected bythese flanges to be made without interference with each other, the foldmade by the tapered portion 3 being efiected'more rapidly and beingcompleted somewhat in advance of the completion of the fold formed bythe less sharply inclined portion 4. In

' order to permit the tip of the, fold formed by the flange 4 to getfrom beneath the opposite flange 3 the inner edge of the latter may beformed with a notchfili which is located substantially opposite thepointwhere the tapered portion 1* of the flange 4 reaches its full width.

The inner end portionsof the folder blades ],-,and 2 extendupwardly-toward the revolving carrier head 74 so as to permit thearticle of merchandise transported thereby to be passed between them,the lower faces 5 and (5 of these portions of the blades being inclinedor curved for the purpose of engaging the projecting end folds of. thewrapper and gradually folding them downward, as will be readilyunderstood upon reference to Figs. 6, 7, S and 10 of the drawings.

To permit the wrapper folding fingers 111 to readily enter between thefolder blades 1 and the inner ends of said blades are preferablyrounded, as at'l 2, and in order to afford the said folding lingers 111suiiicient clearance to permit them to readily travel between the saidfolder blades and to be freely withdrawn. therefrom the inner facesof'the folder blades 1 and 2 are beveled or cut out, as at 1, 9 for asuitable distance forwardly from their inner ends, If desired the upperfaces of the folder blades 1 and 2 may be provided with inwardlyprojecting i flexible retaining strips 127 which extend from thedelivery ends of said blades approximately to the path of travel of therotating folding devices mounted on the carrier head 74:, the completelywrapped ai ticles being thus certainly retained in the chute until theyreach the delivery end thereof.

Pivotally mounted on the supporting member 120 is a curved tongue 7 theouter or free 'end of which rests upon the inwardly extending flanges 3and 1 of the parallel folder blades 1 and 2. This tongue, which isapproximately the width of the article to be wrapped, may be formed ofthin steel and is preferably curled at one end to form an eye or bead 7which may be inserted inadrilled and slotted aperture with which thesupporting member 120 is provided, the tongue 7 being thus pivotallymounted on the supporting member 120 in a simple manner which permits itto have sufficient movement in all directions to prevent it from bindingagainst the folder blades 1 and 2.

As shown in the drawings the tongue'7 is preferably circularly curvedand is sodocated adjacent to the revolving carrier by which the articleis transported that it affords a support for the article of merchandiscafter the latter has been released from the holder 74 and is beingpushed forward by the ejector arm 96 of therotating carrier head. Thetongue 7, as more particularly shown in Fig. 12, is also preferablyfashioned with a centrally disposed groove or depres-a tongue 2, as moreparticularly shown .in

turned back neatly by the inwardly extending flanges 3 and 4 of thefolderblades. In the particular embodiment of pivoted tongue 7 isdeepest adjacent to the pivoted end in order to'per'mit a releasingmovement of-the article holder 74 just after the .article which is beingwrapped enters upon the tongue, thesmallness of the are described by thearticle holder in releasing the article necessitating somewhat morespace for the operation of the holder than that allowed by the arcbounding the path of travel of the article.

- The operation of these folding devices will be readily understood froman examination of Figs. 3 to 11, inclusive, of the drawings. Thewrapping of the article of merchandise having reached the stageillustrated in Fig. 6, the continued rotation of the carrier head 79causes the partially wrapped article to pass between the folder blades 1and 2 as shown YatYbeing-at this time released and the article ofmerchandise being supported on the curved tongue 7 and ejector arm 96 ofthe carrier. During this period the end folds 8 of the wrapper move incontact with the curved lower faces 5 and 6 of the folder blades 1 and2, respectively, and are gradually folded or forced downwardly, as moreparticularly shown in Fig. 10. When the article being wrapped reachesthe tapered portions 3", of'the flanged blades the end folds 8 of thewrapper are carried upwardly against the under side of the thin tongue 7,one end'fold carried upwardlyin advance of the and both folds otherpassing to. the upper side of the inwardly extendingflangesdand 4 of thefolder blades, as previously described. As the article, now completelyWrapped, is pushed onward toward its point of. delivery it is slippedoff the end of the curved tongue 7 and is supported throughout theremainder -of '1tsx..travel by the inwardly extending flanges 3 and {iof the folder blades."

Having thus described my invention, what I claim and desire. to secureby Letters the invention shown in the drawings the groove in the.

in Figs. 7 and 10, the article holder pushedv forward by the a being.tion with a pivotally mounted of folder blades between which the articlepasses, said folder blades having inwardly projecting flanges forming athe said pivoted member.
